county 0' Bronx, and S tate of New York,

have invented a new and useful Door-Lock, of which the following is a full, clear, and exact description.

The present invention relates in general to doorlocks and hasreference more particularly to -a combined permutation and key operated door lock.

The primary object of the invention is to provide a lock which may be operated by either a key or a combination so that in the eventthat the key is not accessible any one knpiwing the. combinationmay unlock the A further object of the invention is to construct the lock of a minimum number of parts and to so arrange thesame that the lock may be manufactured at a comparatively modest cost and be easily installed in a small space without materially reconstructing the customary openings which are .made in doors and the like to receive'the conventional forms of locks and latches.

With these and other objects in view the invention will be more readily understood upon reference to the accompanying drawings and following detailed description the novel points thereof being pointed out in the sub-joined claims. In said drawings F igure 1 is a side elevation ofthe look as applied to doors.

F 1g. 12 is a perspective View of the semicircular disk shaped keys which are used to lock the key barrel on which the tumblers are mounted.

Fig. 13 is a perspective view of a semicircular disk shaped key which is used for the same purpose as the key referred to in Fig. 12, and

Fig. 14 is a side'view of the key for the lock.

Referring to the drawings in detail the lock proposed by the invention is especially Y adapted for doors to which end, in its preferred-form, it is associated with the door A in substantially the same manner as a conventional form of lock in that it is; used in combination with an escutcheon plate B and a knob C which isarrangedto manipulate the ordinary latch D. In one form of conventional door locks the latch D at all times may be manipulated by the knob G and the door is normally unlocked withtli'e exception of course thatthe latchD maintains it closed. When, it is desired to lock the door, a bolt such, as E usually carried beneath" the latch D is manipulated to unlocked position by a' key which is inserted in the look through a key-hole in the escutcheon plate.

'lt-very often happens that the key is often 'findsjthat they have been locked out and no chance of obtaining an entrance without the key. According to 'the present'invention it is proposed to-provide as heretoforestated,

a combined permutation and key operated lock to which end provision is made whereby the'boltE may be either locked or unlocked by the combination or by the key. Thus it will be seen should the key to the lock be lost the door may be either locked or unlocked by a combination. With this end in view and according to the preferred construction of the invention the key barrel 1 (see Fig. 11) comprises a tubularme mber with the key slot 2 made therein to receive the key 3. The inner end of this barrel is reduced in thickness to provide a rectangular extension-4 which is made to engage the end. F of the bolt E so that rotation of the barrel 1 by the key 3 will slide'the bolt E to and from locked and unlocked position till tlti

The bolt Eis mountec the housing G with the guides H arranged to are proper sliding movement of the bolt through .i ing 1 in the face of the housing bl. The key barrel 1 is so-axially received in the bier barrel and in which it is tr when manipulated by the key 3 the combination arrangement; which will be presently. described. This tum er barrel 5 is lined against either longitudinal or rotary movement by the collr 6 which is mounted on the barrel intern to its ends. Positioned adjacent tl flange 6 f split post '5' between t1 vertical coniror 1r; faces of which is pivoted the dog i ng controlling device 8 one end of which terminating m a downwardly presented finger 9 extends through a slot or opening Iitlin the top of t l 5 n t t it? the tumbler arre in [rent o me pos the extreme end of the nngerbeing received in'aslot or opening 11 in the end of the key slot 5?; in the key barrel 1, So long as the linger 9 of the controllin or (longing device 8 is presented through 1g and iiito'the slot ll the key barrel l l be held against rotary movement in the tumbler barrel 5, thus it will be seen to unlock the lock, the ringer 9' of the dogging or controlling de vice 8 must be disengaged tram the slot ll. lit therefore follows that this dogging or controlling device is a common control for both the permutation and. the andmust be manipulated in each case by separate means. i W hen the he is inserted in the slot 2 of the barrel 1 rsee he end of the lrey on beinginserted willraise the finger 9 out of the slot Tilpern g the key barrel to be turned to ma ate the bolt 1%. on the taco of the flange is provided to in duce a lifting effect on the under side of the end of the dogging device opposite the finger 9 which will normally maintain the linger in locking engagement with the barrels l and 5. The strength this spri g is such as to rmable it to be overcome in. King the dogging device by thelre; flo maintain the key barrel 1 in the tumbler barrel to permit rotational the irey barrel, and at the same time preventing a longitudinal move ment of the key barrel the tumbler barrel is provided with a pair of slots 15 on its top which extend about 90 about its circu ference and with a single slot as at 16 which is substantially the same as the slots 15 with the exception that it is-on the bottom of the barrel and located nearer the end of the barrel. The key barrel is provided with a like number of grooves 17 which extend continuously around the barrel a d made to register with the slots 15 and the turnbler barrel Tdeceived'by the ots 15 are a pair of semi-circular di i: keys 18 which are seated in the slots llspring 13 with one endfixed as at 14,

provided Wltfi radial slots 19* which are of a size to leave an unobstructed opening for the key through the key slot The single key 20 which isreceived by the slot 16 terminates with its end received in the third groove in the hey barrel. its this key is presented. on the under of the barrel it need have no slot to accommodate the key. These lreys are confined in the slots 15 and it so as not to leave them protruding-above the circumference of the barrel 5.

As so far described it will be readily seen wherein a lrey such as 3 inserted in the key slot 2 ot the barrel 1 will raise the finger 9 of the dogging device 8 and release the key barrel 1 so that it may be rotated relative to the tumbler barrel 5 and with the rectangular end i manipulating the bolt E. Just as soon as the key 3 is withdrawn the influence of the spring 18 will present the linger 9 in looking position relative to the two barrels and further manipulation of the boltll will be prevented.

in the absence of the lreythe combination must be manipulated to actuate the dogging device and leave the key barrel 1 tree to be rotated. in the first place the key barrel is provided with a manipulating knob 21 which is presented on the extreme end of the barrel and lined thereto in any suitable manner such as by the pin 22. With this knob the barrelmay be rotated when properly released. its stated the flange 5 is mounted intermediate the ends of the tumbler barrel This flange is provided. with a concentric collar or annular abutment 23. lhe tumblers for the combination according to the showin, .1 made are three in number, namely 24, 25 and all ot/ which being coaxially mounted with freedom of rotation on the tumblerbarrel 5, the first 0t which, namely is adapted to bear against the annular collar 23. All these tumblers are provided with annular slots 27 28 and 29-all of which being of the same size so thatwhen brought into registering relation to each other they offer a' relatively long slot. The tumbler barrel is provided with diametrically opposed longitudinal grooves 30 made to receive the tongues 31 of the rings 32 which are positioned between the confrontingfaces of the tumblers. An annular face plate 33 is provided on the outside of the lock the same having radial bolts 3% extending from its inner face. longitudinally on both sides of the tumbler barrel with its ends extending through the ears 35 on opposite sides of the flange 6 and terminating through openings made to receive them in the housingr Suitable nuts 36 being threaded on the bolts so hat they may be screwed up to bear again's the cars 35 draw the face plate 33 toward the flange it and confine the tumblers longitudinal movement on Mill inseam? the barrel 5. Suitable nuts 37 are also provided for mounting the housing G to the door A by these bolts. Go-axially mounted on the inside of the face flange 33 is a manipulating disk38 for the tumblers. This disk is provided with a manipulating knob 39 centered on the outside of the face plate 33. through-which the barrel 5 extends and a cam slot 40 in its circumference, the purpose of which will be presently described. Locat'ed on the inner face of this disk 38 is a lug 41, the purpose of which will also be described presently. Each of the tumblers with the exception of the one represented as 24, which is a plain face bearing against the collar 23', are constructed with lugs 41 on one face and grooves 42.0n their opposite face. These grooves are produced in a manner to leave annular flanges 43 on which are mounted with a limited rotatable movement ring members 44. These grooves 42 are constructed with relatively short slots 45 'made to receive abutments 46 on the annular ring members 44. While the grooves 42' and the annular rings 44 with their abutments 46 are constructed alike in each of the tumblers,

' the slots 48 while of substantially the same size are of course positioned at diametrically opposite points in the grooves 42 the purpose of which will be obvious upon a further reading of thedescription. As stated, each of the tumblers with the exception of the a lug 41 whichis presented in the groove 42 of an adjacent tumbler. It therefore follows that by manipulating the knob 39 and thus rotating the manipulating disk 38 the lug 41 on the disk 38 will sooner or later contact with the abutment 46 in the groove of the adjacent tumbler and when this contact is made further rotation of the disk 38 will bring its corresponding lug in contact with the abutment of the groove of the next tumbler. By. a still further rotation of the knob 39 in the same direction, the lug 41 on the intermediate tumbler namely 25 will be brought into contact with the abutment 46 in the groove of the last tumbler, namely 24, whereupon all of the tumblers are rotated in unison by the knob 39. Say for instance, the knob 39 in accomplishing the result just mentioned has been rotated to the right. Just as soonas the pointer 47 The disk 38 has an axial opening has been presented opposite the proper graduation on the face plate 33 it will be known that the tumbler 24 has'been rotated to present its slot 27 in the desired position. The manipulating knob 39-is then reversed or rotated in a reverse direction whereupon i the tumbler 24 will have been released. As the lug 41 on the adjacent tumbler will travel in the groove 42 of the tumbler 24 in a direction away from the abutment 46, at the same time the lock on the tumbler 24 will contact with the abutment 46 in the tumbler 25 and bring this tumbler to the desired position with its slot 28 coinciding with the slot 27 in the tumbler 24. .The knob 39 is now turned to the right whereupon the lug 41' on the manipulating disk 38 will bring the slot 29 in the tumbler 26 in register with the slots 27 and 28.. The lmob 39 will then again be rotated in a direction opposite to this last rotation until the camslot 40 therein registers with the slots, 27, 28 and 29. With the tumblers in this position the arrangement is such as to permit the weighted yoke 47 which is pivotally mounted on the spindle 48 which in turn is j ournaled as at49 and 50 to drop into the slots 27, 28, 29 and 40 and in so doing it will have a wiping connection with the end 51 of the dogging device 8 which is presented'in the path of the weighted yoke whereupon the influence of the spring 52, which is stronger than the spring 13, the

weighted'yoke will rock the dogging device tumblers are not registered to present a relatively long opening the yoke will ride over the tumblers, but just as soon as the combination has been arranged to register the slots in the tumblers the yoke will fall in to them and in so'doing will raise the dogging device as previously described. Of course the combination as set. forth may be varied as occasion demands and the number of tumblersbe more or less according to the arrangement of the combination.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows 1. In a lock, and in combination, a tumbler barrel, a key barrel rotatably mounted in the tumbler barrel, and adapted to actuate the bolt of a lock, means for controlling the rotation of the key barrel and separate means for independently actuating said controlling means, comprising respectively a key received by the key barrel and a permutation mechanism co-acting with the tumbler barrel.

2. In a lock, and in combination, a turn bler barrel, rotatable tumblers on said barrel, a key barrel rotatably mounted in the tumbler barrel, and adapted to actuate the bolt of a lock, means for controlling the rotation of the'key barrel and means for actuating said controlling means, comprising a key received bythe key barrel, in one instance and themanipulation of the tumblers on the tumbler barrel in another instance. 3. In a lock, and in combination a tumbler barrel, a key barrel rotatably'mounted in the tumblerbarrel and adaptedto actuate the bolt of a lock, means for controlling the rotation of the key barrel, and dual means for actuating said controlling means. 7 4.
